The origin of the phrase "hit the roof" is not definitively known, but it is believed to have originated in the mid-20th century. The expression likely draws on the image of someone becoming so furious that they metaphorically "hit" or "explode through" the roof, symbolizing their extreme anger and emotional outburst. It is typically employed to describe situations where individuals become explosively furious, often in response to unexpected or provocative events. This expression is commonly used in personal relationships, such as during arguments, conflicts, or when confronted with betrayal or deception.

The phrase "go ballistic" originated from the field of military technology and ballistic missiles. Ballistic missiles are known for their high speed and unguided flight trajectory, making them difficult to intercept. In the 20th century, the term "ballistic" came to be associated with explosive and uncontrolled movements. The idiom is often used in situations where someone feels deeply provoked, betrayed, or confronted with unexpected surprises. It can be applied to heated arguments, confrontations, or instances where individuals feel a sense of powerlessness or injustice.

The phrase "blow one's top" originated in the mid-20th century, likely in American English. The expression uses a metaphorical comparison to the release of pressure from a container, like a pressure cooker or a kettle, when it reaches its boiling point. It can be applied to instances of heated arguments, confrontations, or situations where someone's anger becomes uncontrollable.
